What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Grand Seiko SBGZ003

Grand Seiko SBGZ003 owners and reviewers widely praise its classic 38.5mm x 9.8mm dimensions and the meticulous perfection of its craft, with some calling it the sexiest Grand Seiko ever seen. The Spring Drive caliber 9R02 offers an 84-hour power reserve. Some find the dial's color off-putting, and the $57,000 price is a significant barrier for many. On balance, owners and reviewers rate the Grand Seiko SBGZ003 highly for its stunning "carved" dial and Micro Artist Studio finishing.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
